This is a maintenance release to fix a critical bug and threesecurity issues; we urge all users to upgrade.

Please report bugs using the issue tracker at github: https://github.com/bitcoin/bitcoin/issues

How to Upgrade--------------

If you are running an older version, shut it down. Waituntil it has completely shut down (which might take a few minutes for olderversions), then run the installer (on Windows) or just copy over/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

If you are upgrading from version 0.7.2 or earlier, the first time yourun 0.8.4 your blockchain files will be re-indexed, which will takeanywhere from 30 minutes to several hours, depending on the speed ofyour machine.

0.8.4 Release notes===================

Security issues---------------

An attacker could send a series of messages that resulted inan integer division-by-zero error in the Bloom Filter handlingcode, causing the Bitcoin-Qt or bitcoind process to crash.Bloom filters were introduced with version 0.8, so versions 0.8.0through 0.8.3 are vulnerable to this critical denial-of-service attack.

May this version be mostly free of bugs so I don't have to do this again!

Installing only took a few seconds. I do have a bug through the last two versions though. My bitcoin client will freeze the first time I open it. I have to force close the client and the second time it will open up perfectly fine!

It's verifying blocks now.... 23:30 is the time.... When I checked again at 23:35 everything was working, up to date and synchronized!
